This is an intense book in that you cannot read through it rapidly. It requires quiet time where you digest what the author is saying about our God and you are overcome with God's majesty and His holiness.
You have to read this book in small amounts and absorb what you have read. One of the best books I have ever read. We have shared it with many people already and everyone says the same thing - it's a very thought-provoking book. I highly recommend it.
